Caroline County delays vote on state‑mandated solar and battery rules amid safety and water concerns

Caroline County supervisors spent more than three hours on June 23 reviewing TXT03‑2026, a staff‑draft set of zoning changes required by new state legislation that takes effect July 1, 2026, and paused action to give supervisors time to refine restrictions on solar farms and associated battery energy storage systems.

Planning staff presented the draft as a compliance package that adds new definitions, requires applicants to hold community meetings, prescribes setbacks and screening, and reintroduces a solar section with decommissioning, vegetation, and reporting requirements. "The legislation... will become effective on 07/01/2026," planning presenter Mister Hughes told the board, urging prompt action to meet the deadline.

The technical and emotional focus of the meeting was battery energy storage. Fire Chief Loftus told supervisors that storage systems pose four principal hazards — fire, explosion, toxic plume and long‑term environmental contamination — and recommended adoption of NFPA‑855 standards for hazard analysis, emergency response plans and training. "All energy storage facilities will comply with all provisions of NFPA 855 as amended," Hughes read from the draft and Chief Loftus expanded on the operational needs: spacing of containers, on‑site suppression and plume analysis for evacuation planning.

Residents urged caution. "Caroline County is not for sale," resident Rick Hanley said, asking the board to make industrial solar and battery projects difficult to approve and to prioritize farmland and water resources. Other speakers described limited local firefighting water supplies and questioned how contaminated runoff or fire‑suppression water would be contained and removed without exposing neighbors to hazardous residues.

Board members and staff debated numerous technical choices in the ordinance draft: whether to set a fixed perimeter review distance (a 150–200‑foot range appears in the draft), whether buffers may be planted at an initial maximum height of 3 feet, how to require decommissioning financial assurances (irrevocable letters of credit, bonds or cash), whether to count salvage value against surety, and how much on‑site water storage to require for suppression (staff proposed a metric tied to the volume needed to fill five containers rather than a single fixed gallon amount). Planning staff also noted state code prescribes some standards and limits county discretion on certain setback and planting minimums.

Supervisors flagged several additions they want in the draft before any adoption: a requirement for battery‑conditioning and monitoring systems that report temperature, gases and charge/discharge cycles; a requirement that contaminated runoff be stored in lined containment and removed by licensed hazardous‑waste haulers (with receipts); mandatory root‑cause analyses and post‑event reporting; and stronger decommissioning guarantees that do not over‑rely on speculative salvage credit.

The board did not vote on TXT03‑2026. County counsel and staff warned that any material changes after adoption would trigger a new public hearing; to avoid procedural error supervisors agreed to continue the matter and asked staff to circulate a revised draft before a reconvened meeting set for June 29. "If it's something you don't want, you don't have to approve it," the planner told supervisors, stressing that the code creates a process but does not compel approval of any particular special exception.

What’s next: The board will receive an edited ordinance reflecting supervisors' changes and hold a continued meeting June 29 to decide whether to adopt TXT03‑2026 or send a revised draft for additional public review.
